Ulrik Lund Andersen is doing research in quantum information technologies and quantum optics and he is the head of the quantum information group at the department of Physics.

A quantum computer can perform calculations much faster than a standard computer and quantum commincation systems can transfer information with unconditional security. The potentials of such systems are therefore unlimited. In our research group we work partly towards understanding the physics behind quantum information and partly towards developing new quantum technologies. We generate so-called entangled optical states, which have some weird properties that can only be understood through quantum mechanics, and which are the main ingredients in many quantum protocols. We are also working towards the creation of a strong coupling between a diamond nano-crystal and a single photon which may lead to gigantic non-linearities and the development of quantum gates.

Technical University of Denmark

For almost two centuries DTU, Technical University of Denmark, has been dedicated to fulfilling the vision of H.C. Ørsted – the father of electromagnetism – who founded the university in 1829 to develop and create value using the natural sciences and the technical sciences to benefit society.

Today, DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increase and develop our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
